I just sent a updated xdf for the BMW 506 chip number 965
This has many updates from the one that is in the download section.
It has the launch control/2 step rev limiter, corrected the scalars for the speed limiter, found the table for the IAC (idle air control), found the tables for Closed loop ( what engine load and rpm it is enabled and disabled) just to name a few. I set up levels in the xdf so to see everything you need to make sure the tab on the top of tunerpro all the to the right is set to all levels. I also have found how to turn off the CEL on the dash for any codes,but have not found out how to disable the codes altogether. This is not included in the new xdf. If anyone has any info on how this is done please email me. If anyone needs a CEL light turned off you can email me your bin file. I have been getting a lot of questions about tuning for larger injectors and tuning for E85. So I wrote up some info about how to do this. I think I may just post it up here.
I also sent a updated xdf for the 413 red label also. Not many changes to it. I always suggest updating to the 506 bin if you can.

Also please make sure the xdf you are using matches the bin file. You can always find the bin file number under ''BMW chip number" This is the most common issue I hear.
